Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531594, here are decompositions:

5 + 531589 = 531594
13 + 531581 = 531594
23 + 531571 = 531594
43 + 531551 = 531594
47 + 531547 = 531594
73 + 531521 = 531594
97 + 531497 = 531594
113 + 531481 = 531594

Showing the first eight; more decompositions exist.
